I want to make tall grass to stick out of one tier of a cake. It should look like the tall grass you would see at a beach. I don't want to use fondant because the'll be too "fat". I'm looking for thin & wispy, about 2 inches long. I thought of getting wire but I don't want someone to get a piece of wire in their cake.

I think the answer is sugar. I thought if I made melted sugar I could drizzle back & forth over something (wax paper?) and make long strands that I could then break into the lengths I want...will this work?

I've never worked with sugar before so I don't know how to prepare the sugar or if sugar is what I want to use. I see people talk about isomalt and that sounds easier. Is it edible?

I started trying to research sugar work myself and got into complicated instructions. I just want it to be simple. lol

Why not just roll your fondant thin and then cut into strips. Curl the ends over some and then allow them to air dry... they wouldn't be "fat" that way.

use a pasta cutter and do spaghetti. That is what i used to make corn stalks.

I just did poured sugar jewels for the first time this past week. I found this helpful: http://www.chicaandjo.com/2010/04/26/make-hard-candy-jewels/
I used regular sugar rather than isomalt, so I'm not sire about iso, but I thought it wise to start with stuff on hand. Iso has to be heated higher than sugar but can be remelted (or so
I'm told). But if you follow the sugar directions in that link, I don't see any reason why it couldn't be poured onto parchment or aluminum foil to make your grass, as I did a lot of this inadvertantly while doing the sugar jewels. Also, I had extra sugar that wouldn't fit into my molds, and I was playing with it when it had cooled down enough to handle, and I wad forming cool shapes by hand. That could work for you, but I was just playing around; I'm not an expert to tell you more about it.

I have used the very, very thin white chinese noodles that are packaged as a bunch for various items, tall grass, whiskers, stalks. They hold up and keep there shape. I just break them to the size I need and they can be painted to whatever color you need using food color. Good luck!
